# Personas | AI Studio
> Create and manage personas in Collate AI Studio.
# Personas
A persona defines how an agent thinks, communicates, and approaches tasks. It acts as the agent's identity — shaping its expertise, tone, and the instructions it follows when performing work. When you create an agent, you assign it a persona to control its behavior.
## System Personas
Collate includes the following built-in personas. System personas are pre-installed and cannot be deleted.
| Persona | Internal Name | Description |
| -------------------------------- | --------------------- | --------------------------------------------------------------------------------------------------------- |
| **Data Analyst** | DataAnalyst | Expert data analyst specialized in business intelligence, statistical analysis, and data visualization. |
| **Database Administrator (DBA)** | DatabaseAdministrator | Expert database administrator skilled in database management, performance tuning, and query optimization. |
| **Data Engineer** | DataEngineer | Technical expert in data pipeline development, infrastructure optimization, and data integration. |
| **Data Steward** | DataSteward | Data governance expert focused on data quality, compliance, and metadata management. |
